Hey, I really want to give this app a 5 stars. But i am experiencing problems in this app. When i tap on settings or any other option or logo for example, it doesn't open instantly, I need to wait for 5 to 6 seconds. This is not my device's issue, because scrolling works perfectly fine. For more information, I am using a phone from Samsung Galaxy A series. Please check for any issues. Thank you guys. You are doing a wonderful job.

Hi, Althaf!
Could you please try a few basic troubleshooting steps? Oftentimes, uninstalling and reinstalling the app and/or closing any background apps on your device solves any issues you could be running into. If the issue persists, please submit a support request in our Help Center: http://khan.co/KA-support.
Hope this helps!

The app itself is amazing, but there could be more done to it. It's too much navigation, and every video you click on, it's always that same person talking. Another thing that needs to be added is ELA, social studies, history, health, and engineering. I would give this 5 star if you added these things, and I will recommend this to all my friends and family if you added these.

Ever since Covid, I've loved Khan Academy. Its free math courses allowed me to get ahead, and their customer service is in my experience, unmatched. I once had an issue (that was completely my fault) that I needed help from the Khan Academy team to fix. When I sent in a request, less than two minutes later, they had fixed it and notified me. This is truly my favorite app for learning.
